libpcre: Improve the recipe

- Improve the cross patch to determine *_FOR_BUILD in configure

- Leverage the fact that autotools.bbclass handles *_FOR_BUILD now

- Drop the now unnecessary do_compile override

- Drop the do_split_packages

- Split out packages for pcregrep, pcretest, in addition to libpcrecpp and
libpcreposix

- add nativesdk to BBCLASSEXTEND as well as native

- the patch was imported from meta-mentor layer on yoctoproject git server
http://git.yoctoproject.org/cgit/cgit.cgi/meta-mentor as of commit id
62f819b97e356c1d7468fbccbf3a3ceed78b09a8

- broken up the original patch in two parts, this part contains some
improvements to the recipe and the cross patch

-Upstream-Status: Inappropriate [configuration]
+Upstream-Status: Pending
 
-To be upstreamable, this patch requires check for *_FOR_BUILD, otherwise
-it needs to pass special variables.
-
-It would be nice to implement per-target compiler specification to
-automake, as it is done for linker.
-
-Even better it would be nice to implement native build time targets in
-automake.
